Text to speech, transcription, voice cloning and uncensored LLM completions for AI agents, x402 paid, USDC on Base. Verified route: POST /v1/audio/speech at $0.005, taking {input, voice} and returning MP3 audio. At verification a non-fixture sentence produced 48 KB of audio whose bytes were parsed rather than trusted: a valid ID3v2.4 tag followed by a real MPEG frame header at 160 kbps and 48 kHz, roughly 2.4 seconds long and not silent. The audio was not transcribed back, so the badge covers delivery of genuine audio rather than the fidelity of the speech or the voice selection. The other four routes, transcription at $0.01, cloning result at $0.01 and the two LLM completion routes at $0.02 and $0.035, are listed but not payment verified. Base only.
